Like its bigger siblings, the A-1 ver.2 is a completely non-NFB design: no global negative feedback loop of any kind, prioritising signal purity and transient life over tidy measurements. The result is the vivid, three-dimensional, alive-sounding presentation that has made Soulnote a cult name among the world's high-end listeners.\u003c\/p\u003e\n\n\u003ch2\u003ePerfectly Balanced, Discrete, No Feedback\u003c\/h2\u003e\n\u003cp\u003eThe A-1 ver.2 delivers 80 watts per channel into 8 ohms (120 watts into 4 ohms) from perfectly balanced, discrete non-NFB circuits. Carefully paired output transistors with low Cob and high Ft characteristics keep the signal fast and clean, while volume is handled not by a conventional potentiometer but by a relay-switching balanced attenuator — preserving purity and channel balance at every listening level. It's an amplifier engineered, in true Soulnote fashion, to get out of the music's way.\u003c\/p\u003e\n\n\u003ch2\u003eBuilt Like the Reference Models\u003c\/h2\u003e\n\u003cp\u003eThe ver.2 refinement carries Soulnote's obsessive mechanical engineering down to this price point: direct mechanical grounding via spikes, a symmetrical housing with resonance control, and metallic insulators fitted as standard. Everywhere you look, the goal is the same — drain away vibration and let the circuit sing. With a frequency response reaching from 3Hz to 300kHz and a 110dB signal-to-noise ratio, the A-1 ver.2 punches far above its compact 10kg frame.\u003c\/p\u003e\n\n\u003ch2\u003eWhy You'll Love the A-1 ver.2\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCompletely non-NFB, perfectly balanced discrete circuitry for vivid, lifelike sound\u003c\/li\u003e\n\u003cli\u003e80W into 8Ω (120W into 4Ω) with real drive into demanding speakers\u003c\/li\u003e\n\u003cli\u003eRelay-switching balanced attenuator instead of a conventional volume pot\u003c\/li\u003e\n\u003cli\u003ePaired low-Cob, high-Ft output transistors for speed and clarity\u003c\/li\u003e\n\u003cli\u003eReference-grade build: spiked mechanical grounding, resonance-controlled chassis, metallic insulators\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eWhat does \"non-NFB\" mean and why does it matter?\u003c\/h3\u003e\n\u003cp\u003eNFB stands for negative feedback — a technique most amplifiers use to lower measured distortion. Soulnote deliberately omits it entirely, believing a global feedback loop robs music of its transient life and dimensionality. The A-1 ver.2 is a completely non-NFB design, tuned by ear for a vivid, three-dimensional sound.\u003c\/p\u003e\n\u003ch3\u003eWhy a relay attenuator instead of a volume knob?\u003c\/h3\u003e\n\u003cp\u003eA relay-switching balanced attenuator uses precision resistors selected by relays rather than a continuous potentiometer, which preserves signal purity and keeps left\/right channels perfectly matched at every volume — an approach usually reserved for far costlier amplifiers.\u003c\/p\u003e\n\u003ch3\u003eWill it drive my speakers?\u003c\/h3\u003e\n\u003cp\u003eIn most cases, comfortably.
